    Yes what Ollie said, if its below a certain temp the air con will not come on, i think if you have the* displayed on the outside air temp it will not work.

    But if you press button with windshield icon it should also start the aircon, at least that used to happen

    for the aircon symbol to stay on the outside temp has to be above 5degrees

    You were right, after a night in garage it started working. The outside temperature does matter. :salute:

    this is silly though isnt it.. when you want the a/c to demist the windows you cant because the outside temp is too low.

    I have the same problem and find it hard to stop the windscreen misting up without the aircon . Is this directly linked to the air temp sensor ? if so where is it and can anyone think of a way to fool it into thinking its a bit warmer because I'd rather have a clear screen than know if its a bit cold outside.

    It doesn't just do it for fun, it's to protect part of the A/C system (can't remember which bit), but it's an important design feature.

    ...you could go oldskool and just direct hot air too the windscreen... just a thought :)

    A3/S3 aircon has a windscreen defrost button that does it for you too...

    My brother is an ac engineer and he told me that it will not run in cold weather,as if it did then it would cut out on low presure. The presure of the gas in the system is affected by ambient temp. So this is why it is interlocked with the outside temp sensor.
